Romcenter 4.0 rc2 is out now.
I've made a lot of improvments in this version and long lasting problems have been fixed.
Database connection issues should be solved now. Import and operations speed are also back to normal.
Files and roms browsing are also faster and don't freeze anymore.
No more freezes also during long fixing operations. Interface now keeps responding at any time.
I also did intensive tests with files having readonly flag set. This is now all working fine.

Enjoy this version and keep reporting bugs and crashes reports to fix before the final release.
I will now concentrate on isolating text strings for internationalization.
